In high-mobility cognitive radio networks (CRNs), the fast topology changes increase the complexity of the routing scheme. In this paper, we propose a novel CRN routing scheme that considers the path stability and node capacity. First, a realistic mobility model is proposed to describe the movement of highly mobile airborne nodes and estimate the link stability performance based on node movemen...

For this demonstration, we will present and describe VanetMobiSim, a generator of realistic vehicular movement traces for telecommunication networks simulators. VanetMobiSim mobility description has been validated by a comparison of its traces with TSIS-CORSIM, a benchmark traffic generator in the industry. VanetMobiSim is therefore one of the few vehicularoriented mobility simulator fully vali...

Vehicular Ad-hoc Networks (VANETs) have been recently attracting increasing attention from both the research community and the world of industry. Many related projects have been developed, involving analytical modeling of vehicular traffic, simulation of vehicular environments and real world measurements. Regardless of this effort, no really complete simulation tool is today freely available to...

We develop a stochastic network model for charge transport simulations in amorphous organic semiconductors, which generalizes the correlated Gaussian disorder model to realistic morphologies, charge transfer rates, and site energies. The network model includes an iterative dominancecompetition model for positioning vertices (hopping sites) in space, distance-dependent distributions for the vert...

The individual-based models constitute a set of widely implemented tools to analyze the incidence of individuals heterogeneities in the spread of an infectious disease. In this work we focus our attention on human contacts heterogeneities through two of the main individual-based models: mobile agents and complex networks models. We introduce a novel mobile agents model in which individuals make...

Cars have become essential elements of modern life. But nowadays the increasing number of cars also leads to problems: pollution, traffic jams, wasted time spent in traffic because of traffic bottlenecks, etc.. Traffic cannot cope anymore with the rate of car usage today. Fortunately, in the last years various Intelligent Transportation Systems (ITS) demonstrate innovative services relating to ...

Traditionally, ad hoc networks have been viewed as a connected graph over which end-to-end routing paths had to be established. Mobility was considered a necessary evil that invalidates paths and needs to be overcome in an intelligent way to allow for seamless communication between nodes. However, it has recently been recognized that mobility can be turned into a useful ally, by making nodes ca...

Much progress can be observed in the domain of Vehicular Ad Hoc Network (VANET) research looking back at the last decade. It can be seen that studies of vehicular communication protocols in the context of VANETs are typically based on simulation models. This approach has two major prerequisites: First, detailed network simulation of all layers of communication protocols is necessary as provided...

This paper describes recent work toward developing a terramechanics-based modeling and validation infrastructure for characterizing the Curiosity rovers mobility properties on the Mars surface. The resulting simulation tool, ARTEMIS (Adams-based Rover Terramechanics and Mobility Interaction Simulator), is composed of a MSC-Adams dynamic rover model, a library of terramechanics subroutines, and ...
